BRUSH;

Specification of Letters Patent.

Patented May 29, 1906.

Application filed December 18, 1901. Serial No. 86.361.

To all whom it may concern-.-

Be it known that I, J OHN P. WIENS, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented a new and useful Improvement in Brushes, of which the following is a description, reference being had to the accompanying drawings, which are a part of this specification.

My invention has relation to improvements in that class of brushes commonly known as dustless sweeping-brushes in which a series of absorbent tufts are bordered by non-absorbent tufts, the absorbent tufts adapted to have a more or less volatile oil, such as kerosene or gasolene, fed thereto.

One of the primary objects of my present invention is to provide a cover for the back stamped from a single sheet of metal and bulged upwardly to form an oil-chamberbetween said cover and the back and also advisably having side flanges extending downwardly against the sides and ends of the brush-back and preferably beneath said back for a short distance.

It is an advantage to provide but a single back-piece for a brush and at the same time provide for all the tufts being composed of long material doubled centrally and the butts thereby formed inserted into openings eX- tending through said single back-piece, which openings lead from the interior of the recess or cavity, and held in place by being wiredrawn, but yet at the same time the. arrangement must be such that the non-absorbent tufts will not be exposed to the oil in the recess or cavity of the back.

Another important object, therefore, of invention is to secure this desirable resu t.

With the above primary and other incidental objects in view the invention consists of the devices and parts or their equivalents, as hereinafter set forth.

In the accompanying drawings, Figure l is an elevation of a brush embodying my improvements. Fig. 2 is a plan view with the handle removed and a portion of the top broken away. Fig. 3 is a cross-sectional view on the line 3 3 of Fig. 1, and Fig. 4 is a detail fragmentary view of the handle looking on the under side thereof, and Fig. 5 is a transverse section of the brush with the cover removed.

Referring to the drawings, the numeral 7 indicates a brush-back provided with a series of openings therethrough, said openings preferably arranged in series of longitudinal lines. One or more of these lines of openings may be utilized for securing therein the absorbent tufts, and the remaining openings are utilized for securing therein the non-absorbent tufts. central line of openings (designated by the numeral 8) as the openings in which the absorbent tufts 9 are secured and the remaining lines of openings (designated by the numeral 10) as the openings in which the non- Inthe drawings I have shown the absorbent tufts 11 are secured. The absorbent tufts 9 are preferably of palma fiber or other suitable absorbent material of sufficient length to enable them to be doubled or folded centrally and the butts thereby formed inserted into the openings, and the non-absorbent tufts 11 are of Tampico fiber or other suitable non-absorbent material of sufficient length to permit them to be also doubled or bent centrally and the butts thereby formed inserted in the openings. The butts of the fibers referred to are passed upwardly in the openings sufficiently far to enable wires 12 to be inserted through the loops formed at the bend of the fibers, the said wire being drawn tight, so that the fibers are securely held in place. Now as the top of the brush-back forms the bottom of the oil recess or cavity and as said oil should only feed down through the openings 8, in which the absorbent tufts are secured, it is necessary that the openings 10, in which the non-absorbent tufts are secured, should be made impervious to the feed of oil therethrough and onto the non-absorbent tufts. My invention therefore contemplates plugging up the said openings, and this may be accomplished in any desirable manner, although I prefer to do this by applying a suitable oil-proof cement 13 in the openings 10 and over the butts of the non-absorbent tufts, forming plastic plugs, as most clearly shown in Figs. 2, 3, and 5. This cement is also applied over the entire top of the brush, whereby said top, which is of wood, is rendered imperviousto the escape of the oil except through the central line of openings 8, in which the butts of the absorbent tufts are secured, whereby the oil is free to enter only said line of openings 8 and feed down the absorbent tufts, the said oil preventing the rising of dust, and thereby avoiding a disagreeable feature inherent in the ordinary form of brushes in which the dustless feature is ab' sent.

my invention is the provision of an improved form of top or cover for the brush-back, said 1 top or cover being formed from a single sheet of metal stamped out to the required shape. 3 This top piece or cover is indicated by the numeral 14 and is provided longitudinally with 5 an outwardly-bulged portion, which forms between its under side and the top of the brush-back an interior chamber 15 of consid erable width and capacity. At its side andend edges the top or cover is flanged out-. wardly to form the flat surfaces 16, which rest squarely upon the upper side of the brush-back. I prefer, however, to flange the metal downwardly along the side and end edges of the brush-back, as indicated by the numeral 17, whereby the edges of the wooden back are prevented from wear by contact with hard objects in the operation of sweeping. If desired, also, in order to assist in securing the top or cover firmly in place the lower edges of said top or cover are bent under the brush-back for a short distance, as clearly shown in Figs. 1 and 3 and as indicated by the numeral 18.

The handle of the device is indicated by the numeral 19, and the inner end 20 of said handle, which is shown as a socket to receive the handle proper, is formed with a flat portion 21, said flat portion provided on its under sidewith intersecting or crossed grooves 22 22, which, at the. center or crossing-point, merge into a central opening 23. On the outer side of the top or cover are intersecting or crossed ribs 24 24, which at the intersecting or crossing point are interrupted by an opening 25. The metal of the top or cover where these ribs are provided is advisably reinforced, so that said top or cover may have suflicient strength to resist the strain which is exerted at this point. In adjusting the handle to the top or cover two of the grooves of said handle are made to fit two of the ribs of the top piece. A bolt 26 is then passed through the registering openings 23 and 25, the head of the bolt being against the under side of the top piece, and a winged nut 27 is turned onto the upper threaded end of the bolt in order to securely clamp the handle to the, top or cover. In the drawings the handle is secured so as to extend out at right angles to the length of the brush. If it is desired to shift the position of the handle, so as to extend out at right angles from the opposite done is to loosen the winged nut, turn the handle around to the position referred to,

taking care that the grooves and ribs engage with each other, and then again tighten the winged nut, or, again, if it is desired that the handle should project in the direction of the length of the brush said handle can be swung around so as to extend out from either end and secured in such position by tightening the winged nut.

It will be noticed, particularly from Fig. 3, that the oil-proof cement is also disposed between the inner sides of the flanges 17 of the top or cover and the outeredges of the brushback, whereby the oil is prevented from leaking therebetween and at the same time airtight joints are provided.

For introducing the oil into the chamber 15 I provide the top or cover with an opening, in which is fitted a tube 33, the upper edge of said tube being flanged outwardly. The interior of the tube is threaded, and engaging these threads is a depending stem from a cap 34. When the stem is turned into the tube, the cap is adapted to be brought into engagement with the flanged upper end of said tube, and thereby close the opening. A packing 35 is advisably interposed between this flange and the under side of the cap. When it is desired to fill the oil recess or cavity with oil, thecap is removed and said oil poured through the opening of the top or cover 14.

What I claim as my invention is 1. In a brush, the combination of a brushback provided on its upper side with an oilchamber and having a series of openings extending from its under side upwardly, all of said openings leading into the oil-chamber, absorbent and non-absorbent tufts extending from and secured in the openings, and means plugging up the upper ends of the openings in which the non-absorbent tufts are secured so as to permit the oil to pass from the, oil-chamber only through the openings in which the absorbent tufts are secured and onto said absorbent tufts.
